FOLDING-MACHINE.

To all whom it may concern:

Be it known that I, GARRY J. DORMANDY,

of the city of Troy, county of Rensselaer,

and State of New York, have invented certain new and useful Improvements in F olding-Machines, of which the following is a specification.

My invention relates to folding machines, and more particularly to machines employed to inturn or infold edge portions of the blanks from which cuffs, collars, shirts and other articles are made.

Of the numerous objects and advantages pertaining to the present improvements, several will be enumerated in the detail description hereinafter following; among them may here be mentioned the object of adapting machines of this class to form the infolds upon the edges of blanks with alternatingly overlapping and underlapping corners, by substantially one operative movement, or one advancing movement of the mechanism, instead of two or more operations or movements, as has been attempted by older mechanisms of the same class; this object being ac complished by means of infolders operated in groups or series, that is alternatingly operated to move inwardly preferably with two differing directions of folding movement by the advancing movement of the mechan ism, whereby one series of the infolders will be operated to move inwardly, first in one direction, for example sidewise, and in se quence moved inwardly at a different angle, or endwise; and another series of the in folders at or about the same time will be moved first inwardly endwise and then .in sequence moved inwardly sidewise, thus alternatingly forming the infolds on the edges of the blank with under-lapping and overlapping corners, whereat the edges of the blank can be locked or anchored when sewed. Each group or series will consist of one or more infolders. Any two identical blanks so formed can be interlocked with each other and sewed.

Accompanying this specification to form a partof it there are six plates of drawings containing thirteen figures illustrating an application of my invention with the same designation of parts by letter reference used in all of them.

Of these illustrations Figure l, is a top view of a machine which embodies my in- Specification of Letters Patent.

vention, and which is shown to contain, as is usually though not invariably the case, an expanding and contracting templet, and showing the templet-plates thereof expanded so as to be over the blank, the edges of which are to be infold-ed, and as resting therein with the infolders in a position to be moved inwardly, and the arm by which the templet is operated to descend 011 to, and rise from otf the blank or bed shown as broken off. Fig. 2, shows in top view the same parts that are illustrated at Fig. 1, with the exception that the templet is omitted, and the infolders are illustrated as having been moved inwardly. Fig. 3, is a side elevation of the machine, and Fig. 4, is a view of the underside of the bed or table on which the mechanism is mounted to be operated. Figs. 5 and 6, are perspective views of two of the infolders, Fig. 6 showing also the slide-pinplate F 2 engaged in the slideway Z in an extension of the infolder-bar 1 Fig 7, is a perspective of one of the slide-bars, of which there are two pairs used, with those of each pair arranged at diametrically opposite points to slidingly engage one of the infolder-bars. Fig. 8, is a perspective of one of four smnlar slot-plates, each having an arc-form exterior, and arranged at diametricallyopposite points to connect with the slide-pins of one of the infolder-bars and one of the slide-bars. Each of the slotplates shown at Fig. 8, has a slot formed therein part of which is concentric and part eccentric. Fig. 9, is a perspective of one of four other slot-plates, each having the same exterior arc-form as those shown at Fig. 8, but having the slot formed in each of them made with a centrally located concentric part, and at each end of the latter a connecting slot-part that is eccentric to the ring with which these slot-plates connect. These slot-parts shown at Fig. 9 are each of them arranged to connect with the slidepin of one of the infolder-bars and at diametrically opposite points to have another of them connect with the slide-pin of one of the slide-bars where located between two of the slot-plates shown at Fig. 8, so that the slot-plates shown at Figs. 8 and 9 will be alternatingly arranged in the ring which operates them. Fig. 1 0, is a cross-section taken on the line 2- 2 of Fig. 6, illustrating the method of connecting the slide-pins and slot of the slot-plates; it being in each instance as shown at Fig. 10. Fig. 11, illustrates a blank cut from the fabric and having a form adapted to be infolded by the mechanism herein shown; Fig. 12, a blank in which the infolds have been formed to alternatingly overlap and underlap at the corners and in succession; and Fig. 13, two of the blanks which have been folded as shown at Fig. 12, and placed with their infolded edges arranged to be together with one of the corners of the outer blank shown as turned over and down, to illustrate how the interlocking of the blanks thus infolded can be accomplished at the corners before the blanks are sewed together.

The several parts of the apparatus thus illustrated are designated by letter reference and the function of the parts is described as follows.

The letter B designates the bed constitut ing a support for the blanks to be infolded, WV, the web on the under side of the bed, and R, a to-andfro moving member or slide, shown in the form of a ring, having formed in its upper surface a groove 9 and pro vided with a handle H, by which to be reciprocatingly rotated in an annular slideway G formed in the bed.

The letter T designates a templet for defining the blanks to be folded. Specifically it is of the form having expanding and indrawing plates which when expanded will have on their outer edges the shape of the blank to be infolded. The letter A designates an arm which at its rear end a is hinged to the bed, and at its front end a it connects with a bridge a upwardly projected from the templet stock S, on which connection the templet is operated to descend 011 to, and rise from off the bed. The arm A and connected parts form a convenient means for positioning the templet upon and removing it from the blanks. A counterpoise C" may be employed in con nection with the arm A, the weight or adjustment of which will depend on whether the templet is desired to be normally in elevated or in lowered position. Preferably the counterpoise will overbalance the templet. No claim is made herein to the form of templet or positioning mechanism apart from the combination thereof with other features of this application; on the other hand it is not desired to impose limitations to the precise form thereof, as any well known or convenient positioning mechanism or templet may be employed.

The letters P, P, P, P, designate the tem plet-plates and they are each provided with an upwardly projected slide-pin p and a slide-way 72 formed in the stock S.

The letters E, E, designate plates of which there is one at each end of the stock S, having a slide-way centrally formed in the latter parallel to its sides to receive a slide-bar on the bottom of each of the plates E, which slideways and slide-bars are not shown.

The letters designate a slot that is formed in each side of each of the plates E, and thereat adapted to receive one of the slide-pins p of one of the plates P.

The letter D designates a disk that is centrally pivoted to the stock (Z and the letter (Z designates a handle laterally projected from the side of the disk.

The letters (Z (Z designate links each of which at one of its ends pivotally connects with one of the plates E, and at their inner ends they each connect with the disk D, at diametrically opposite points; whereby when the disk is reciprocatingly rotated the templet-plates are moved outwardly and inwardly.

To the before named parts excepting where used with my novel infolding mechanism I make no claim herein.

I will next describe the infolding mechanism including the slide-ways S the slidebars I engaged therein, used in actuating the infolders, the infolder-bars I and the folder-plates or thin blades m m which actually contact the blanks, and their oper ating mechanism. The thin infolder plates .or parts an), m are rigidly secured under the infolder bars I and with the latter may be said to constitute the infolders.

tinct heavy parts or bar-parts and thin or plate parts connected together, may be varied either in construction, form or style from what is shown.

The letters S designate slide-ways of which there are two at the front and two at the rear of the machine bed, all of which are arranged to project inwardly from the outer edges of the bed in parallel direction.

Each of those slide-ways S 1s produced by and between the bars 6 72 of WlllCll there are two for each slide-way, secured to the machine bed by bolts 7).

The letters I 1 1 I designate four slide-bars, they being L-form bars, each parallel to each other, and outwardly projected from the short-arm at right-angles thereto.

The letters P, I 1 I designate the infolder-bars each of which is provided with a slide-way i formed in its outer end for the movement therein of the short arm P, of

that one of the slide-bars I which is next adjacent thereto. The slideway S and for the side-bars I and the infolder bars I respectively, may be parallel to the respective sides of the blank adjacent the corner at which such parts are located, or may be at any desned angle to each other, but are The infolders thus shown as constituted of dispreferably at a right angle to each other, in the illustrative machine hereof. Each of the said infolder bars I, is constructed with a laterally and rectangularly projected end bar-part i from the underside of which there is extended inwardly and laterally the end plate-part m The letter m designates a side plate-part which is arranged to project inwardly from the underside of that part of each of the folder-bars 1 designated at i, and which side plate-part m is arranged to extend in wardly in each instance of its use where its inner end will subtend the rectangularly projecting end bar-part i Each of the plate-parts m, as indicated at m, is made to project beyond the inner end of the barpart i of each of the infolder bars 1 and each of these plate-parts m is made to project beyond the end of that part of the folder-bars P, designated the extension of the plate-part m being indicated at m.

it-h the four infolders thus constructed and arranged, when they are moved together inwardly their infolder end plate-parts m and the info-lder side plate-parts m inclose an oblong square with the ends of the infolder plate-part m lapping past each other at m, and the ends of the side plate-parts lapping past each other at m.

To facilitate the movement of the ends of the plates m and m at m and m where overlapping to form a continuous infolding edge and to prevent the ends of the plates so operated from catching in the fabric when moving over it the inner corner edges of the plates are rounded ed as shown at m and the free overlapping end of each of the plates is slightly curved upwardly as indicated at m. Sometimes it is unnecessary to make the adjacent infolders overlappin and I do not feature.

The letters N designate slot-plates of which there are four so designated, and the letters l lesignate four other slot-plates, all of which before designated slot-plates have an arc-form on their inner and outer edges by which they are adapted to be inserted in the annular groove formed in the ring R, and secured therein by screws as shown, so as to move with said ring when it is operated in the annular slide-way G, formed in the machine bed. The letter O designates a slot that is formed in each of the plates N each of which slots has an eccentric slot-part designated at O, and a concentric slot-part each connecting with the other. Each of these slot-plates N has formed therein the slot U, which latter atone of its ends has the eccentric slot-part a and at its other end the eccentric slot-part a, and the intern'iediately centrally located and con nected concentric slot-part a The letters F designate slide-pin plates wish to be confined to thi of which there are four so designated, each of which is adapted to be inserted within a sink or recess R formed in the short-arm Z, of each of the slide bars 1 of which there are two at the front and two at the rear of the machine as before stated. As the slot-plates N and N are alternatingly arranged in the ring R, each pair of the bars P, at the front and at the rear will have one of the plates F immediately over one of the slot-plates i and the other of the plates F of the same pair over one of the slot-plates l, and thus position the slot O of the plates N so as to be diametrically opposite to each other, and also cause the slots U, of the plates h at the front and rear to be diametrically opposite each other. The slide-pin plates F are adjustably connected to the short-arm of that one of the slide-bars I over which it is placed by the slot C and the screw 0 The letters P designate slidepins of which there is one projected downmirdly from the inner end and underside of each of the two slide-pin plates F located at the front and rear of the machine. The slidepin P upon one of the slide-pin plates F at the front of the machine is entered within one of the slots 0 of the slot-plate N thereat, and the slidepin P*, of the other slidepin plate F also at the front is entered within the slot U, of the slotplate N thereat. The slide-pin I, of one of the slide-pin plates at the rear of the machine entered within the slot of the slot-plate h, thereat; and the slide-pin P*, of the other slide-pin plate F at the rear of the machine is entered within the slot U of the slot-plate N located thereat.

The letters F designate slidepin plates of which there are two arranged at each side of the machine. Each of these slide-pin plates F is ararnged within a sink or recess R, formed in the outer arm of one of the folderbars I and thereat adj ustably secured by means of a slot C, in the slide-pin plate and the screw 0 threaded into the outer arm of that one of the infolder-bars T in which said slide-pin plate is located.

The letters P designate slidepins of which there is one downwardly projected from the inner end and underside of each of the two slide-pin plates F located at each side of the machine at diametrically opposite points; with the slide-pin P, of one of the slidepin plates F entered within the slot 0 of the slot-plate N located at each side of the machine and each of the other pins P located within one of the slots U, of each of the slot-plates N where diametrically oppo- Site at the sides of the machine.

The letters 13', designate presser-bars which are each mounted upon the upper ends of posts or studs 11, which latter are extended downwardly through slide passages &

Ann

I slide-pins moving in the slot-plates N located at that end of the concentric slot parts I O, of each of the slots whereat their movement begins, and wherein at the initial movement of the ring they will move without operating the corresponding slide-bars ile the slide-pins of all islet-plates N are ement of the eccentric its U, when the handle direction indicated by lhis initial movement ,tes the rmg R, and fN and N to move jslide-way G, formed presser-bars B and HF studs or bars u, connect has two V-form ends E of which but one is shown (see Fig. 3) each of which ends is provided with two strengthening webs w he letter B, designates a horizontally arranged bar which connects the two ends of the presser-frame said bar being indicated by a dotted line.

The letters M, designate a spiral spring of which there is one arranged beneath the bar B and the table K, at each end of said bar (there being but one of said springs shown).

The letter J, designates a bar depending from the underside of the machine bed and the letters L designate a lever having its fulcrum end pivoted to the lower end of the depending bar J, with the outer end of this lever pivotally connecting with the rod 23*, of the foot-treadle T with the lever L between its fulcrum and its connection with the treadle-rod bearing upon the bar .13 lVhen this foot -treadle is pressed downwardly it pulls down upon the outer end of the lever L and this bearing upon the bar B pulls down the resser-frame and causing the presser V, to bear upon the infolderbars P, and the bars B to bear upon the slide-bars 1 ,to thus press the infolds formed on the edges of the blank as they are between the infolders and the bed with said pressers and presser frame as well as the presser-bars B actuated to rise when pressure is withdrawn from the treadle and the springs M become operative.

The mechanism just described forms a convenient means to effect the pressing of the blanks between the bed and infolders, before the latter are moved outwardly. No claim is made herein to this presser mechanism apart from the combination thereof with other features; on the other hand it is not intended to limit the claims to the use of such presser mechanism, as other convenient forms may be used or all may be dispensed with when desirable.

The handle H, when in position to commence the infolding of a blank on the bed is placed as shown at Fig. 1, with all of the ill. the ow. fi ctuated the slide-pins of one pair of the slot-plates N where located diametrically opposite to each other at the front and rear will each operate one of the slide-bars 1 together with that one of the folder-bars 1", with which it connects by which the latter will be moved sidewise and thus carry a portion of the side edge of the blank over the templet edge thereat, while one of the slide-pins of that pair of the slotplates N of which there is one at each side of the machine at diametrically opposite points, will actuate each of the two folderbars thereat to move inwardly endwise and thus carry the edges of the blank thereat over the templet.

hen the slide-pins operating in the slotplates IV, reach the end of their initial 'anovement in the eccentric slot-parts if, of the slots U in which located, they cease to act upon the slide-bar or infolderbar which they actuated at the beginning; but the slide-pins moving in the concentric slotparts of the slots Q of the plates N at the beginning having by the continued movenent of the ring been caused to enter the eccentric slot-part O become active and operate to move inwardly endwise at diametrically opposite points the infolder-bars irst actuated to move inwardly sidewise; and the slide-pins operating the other dia- "=netrically opposite slide-bars will cause the latter to move inwardly sidewise the infolder-bars which have been actuated to move inwardly endwise at the beginning.

lVhile the slide-pins in the slotplates N are moving in the eccentric parts 0 of the slots the slide-pins moving in the slots U of the slot-plates N pass from the con centric slot-part a, to enter the terminal eocentric slot-parts of the slots U, of each of the slot-plates N and while moving therein the slight eccentricity of the slot-part it, prevents the pins which are moving in the eccentric slot-parts 0 of the slot-plates N from giving a retrograding movement to the folder-bars 1 having their slide-ways in the slide-bars being operated upon.

During the initial movement of the slotplates N, alternatingly placed in the ring R, with relation to the plates N there are formed upon each of the blank-sides at diagonally opposite ends a side infold by the inward movement thereat of the folder-bars and their folder-plate parts m while at the same time there are formed at the other diagonally opposite corners of the blank an end infold by the inward movement of the folder-plate parts m This having been done and the advance movement of the ring continuing the slot-plates N become active to operate the slide-pins of the remaining slide-bars I and the infolder-bars I thus bringing into line the side infolder-plate parts 122?, m of each side, and the end infolder-plate parts m m of each end, the side infolder-plate parts overlapping each other at m*, and the end folder-plate-parts at 712?, the inward movement of the diametrically opposite folder bars I as each is operated by one of the slide-bars I turning down at diagonally opposite corners in the blank one of the end-folds, and the infolderbars I operated directly by the plates 1 in turning down a side infold at the other opposite corner of the blank; so that by one advance movement of the ring R, there is formed on the blank B, an infold upon all of its edges; with the infolds at the ends and sides alternatingly overlapping and underlapping at the corners.

The letters R designate a friction roller arranged on each of the slide-pins P, and P, illustrated as applied to the latter at Fig. 12, the latter showing the same arrangement of slide-pinplate, slidepins and friction roller that occurs when either the plates N or N are used. When the infolds have been thus formed upon the blank the ring is returned to original position to repeat the operation upon a new blank or blanks.

To produce alternatingly underlapping and overlapping infolds at the corners of the blank by one advancing movement of the mechanism I employ a series of infolderbars actuated to move inwardly in one direction, and in sequence to move inwardly in another direction and at the same time to have another series of infolder-bars also arranged to move inwardly in two differing directions of movement to complete the formation of the infolds with overlapping and underlapping corners.

bar, I refer to a movable bar or member to which an infolder plate is attached, and through which the infolder plate derives motion from a so-called slide-bar. Slidebar likewise refers to a bar or member fitted by means of suitable guides or ways securedto the bed to move to and fro. The slide-bars and infolder bars combined form a convenient means of fitting the infolders or plates to move to and fro between an inward and an outward position with two ranges of movement of differing direction, according to my invention. The several slot-plates and slide-pins intermediate these infolder bars and slide-bars and the said ring R, will be understood to form a cam engagement, the cam being a convenient infolder operating instrumentality.

As already made clear, one purpose of my invention is the production of blanks infolded in such manner that any two thereof may be fitted together to interlock or form a lock corner cuff or other article, thereby dispensing with the necessity of employing two machines for folding two blanks that will interlock, or, in a given machine, two distinct infolder operations or adjustments, for that purpose. It will be apparent that since one of two identical blanks to be interlocked must be turned up side down before the two can be fittted together, the form of blank must be one that is symmetrical about at least one center line, either the longitudinal or lateral. When the blank is of a form symmetrical about one, for example the lateral line, it is merely desirable that each interlocking corner upon one side of that center line be formed with its infolds in the reverse order of the infolds of the symmetrically opposite corner. I/Vhen however, the blank is symmetrical with respect to the longitudinal, as well as the lateral center line, as is the case with all rectangular blanks, such as has been selected for the illustrative machine hereof, it is especially desirable that the two folds meeting at each corner should be turned in, in the reverse order of that of both of the symmetrically opposite corners. Thus in Fig. 11 the upper left corner is formed in a reverse manner to that of the lower left corner as well as that of the upper right corner, because in the latter two cases the side fold is turned in after the end fold, while in the upper left corner the end fold is turned over afterward. The lower right corner is obviously formed similarly to the upper left, and either of these is adapted to interlock with either of the other two corners of a similar blank when turned up-sidedown. The advantage is that not only may any two such blanks be interlocked, but either end of one such blank will look into either end of the other, and the operators .Vhen in the claims herein I say infolder attention is not required to select the proper end, in making up a cuff or like article.

By infolder in the claims I mean to include not only the infolding plate which actually contacts the blank edges, but also the infolder stock or body portion if there be one; as a whole the two constitute the infolder. By pressing folds beneath the infolders I mean any such pressing, whether by forcing down the infolders, or otherwise.

In claims l5, l6 and others, where a series or plurality of infolders are recited as having certain characteristics or operation, this merely means that at least two (or perhaps more, but not necessarily all) of the infolders on the machine are to have such characteristics or operation.

In claims 35 to 42 inclusive, certain terms are used, which I explain as follows: Slide device refers to the device including the inwardly and outwardly sliding slide, such. as I and all those concomitant parts which in operation are rigid with the slide, necessarily move with it, and are substantially parts of it. For example, the adjustable slide pin plates F and )ins 1f are parts of the slide device. By movable actuating device I refer to the ring R and all parts which are rigid with and substantially part of it, whether integral or attached. For example, the cam plates N N and the screws attaching them to the ring are included in the movable actuating device. By a direct connection I mean an actually contacting connection, whether rigid, sliding, or otherwise. For example, the infolders have direct connection with the slides or slide de vices. Also the movable actuating device has direct connection with the slide devices, namely by the cam plate of the former contacting the cam pin of the latter. The infolders move in a horizontal plane immediately above the bed. The two slides for each infolder move in the same plane, and so does the actuating ring for the slides. Thus great simplicity is obtained and simple adjustments afford capability of much desirable variation in action.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
